Were you part of the demonstrations in Oakland? Do you have more video or pictures, or links to material already published? Can you shed any light on the flash bang contradictions? We would like to build a more comprehensive picture of what happened.

Also, were you arrested? We would like to hear your story. It is better to email me or contact me on Twitter @AdamGabbatt, as it makes it easier for us to contact you back. Or you can post links in the comments below.
